Habitat
Beheeyem is an extraterrestrial Pokémon. Since arriving in the Desert Resort through unknown means 50 years go, they have since made their home in the northern, foggy areas of Unova's eastern peninsula.
Beheeyem and its pre-evolution Elgyem are the only species who can have Telepathy without it being their Hidden Ability.
Origin
Beheeyem is based on greys, one of the more popular kinds of alien. Judging from Elgyem's Pokédex entry, it and its evolution may also be based on the Area 51alien conspiracies or the Roswell incident. The colored dots on its hands resembles the colorful faces of the invaders in the 1953 War of the Worlds film; the aliens in the film had green, blue and red dots just like Beheeyem's Shiny coloration. Considering its species names, physical appearance, and powers, it may also be based on a brain.
Name origin
Beheeyem is a corruption of the abbreviation BEM, an old-fashioned term used to refer to extraterrestrials.
Ohbem may be a combination of orb and BEM (pronounced as a single word in Japanese). Oh may also refer to 大 ō (large) and bem may also refer to beam (referencing tractor beams from UFOs).
